REINHOLD BETTERMANN, OF OAMBRIA, PENNSYLVANIA.

PORTABLE SASH-SECURER.

SPECIFICATION forming part of Letters Patent No. 283,460, dated August 21, 1883.

A Application filed June 15,1883. (Model) To all whom it may concern.-

Be it known that I, REINHOLD Bnrrnnrmnn, of Cambria, in the county of Cambria and State of Pennsylvania, have inventedcertaiu new and useful Improvements in IVindow-Sash Fasteners, of which the following is aspecification. 3

- This invention has reference to an improved windowsash fastener, which can also be used with advantage as a sashlock; and it consists ofa plate having a rectangular extension at one end, and a lever fulcrulned to the other end of the plate, the lower end of the lever being sharpened at its edge, so as to bite into the guide-rail of the sash, while the shorter upper end projects above the plate and is acted upon by the sash. V

In the accompanying drawings, Figures 1 and 2 represent a window-sash with my improved sash-fastener, showing the sash sup-- ported thereby in raised position, and also looked in lowered position; and Figs. 3, 4, and are respectivelya vertical longitudinal section, an. end view, and a plan of niy improved sash-fastener.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a steel or other plate, which is bent up at one endat right angles to the main part, so as to form a rectangular extension,- a. The other endis bent so as to form eyes I) .b, to which the pivots b b of a lever, B, are applied. The upper rounded-off portion, (1, of the fulcrumed lever B extends above the plate A, while its longer downwardly-extending arm (2 is made wider at its lower end and sharpened at the edge, so as to engage the guiderail of the sash when the device is placed in position for use. A sheet-metal casing, O, is attached by rivets or in any other suitable manner to the plate A, so as to incase the longer part of the lever B.

'The casing O is. of triangular shape, and is open at the side facing the guide-rail of the sash, so that the sharp lower end of the lever B can project beyond the casing and engage said guide-rail.

The sash-fastener is used 'in the following manner: The sash islifted and the upwardlybent portion a of the plate A inserted between the sash-frame and the sash guide-rail. The sash is then lowered so as to rest on theupper projecting end, (I, of the. lever B, its weight throwing the sharp lower edge of the lever against the sash guide-rail, so as to bite into the same and support thereby the sash, as shown in Fig. 1. To lower the sash, it is firstlifted, so as to permit the removal of the fast ener. The fastener is then placed in an inverted position at one of the upper corners of the sash, as shown in Fig. 2, in which position it forms a sash-loch when the sash is attempted to be opened from the outside.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A sash-fastener consisting of a plate, A, bent in upward direction at one end, of a lever, B, that is hinged or fulcrumed to the opposite end of the plate, the shorter upper end of the lever extending above the plate, while the edge of the lower end is sharpened to bite into the sash guide-rail, substantially as set forth. v

2. A sash-fastener composed of a plate, A, being bent upat right angles at one end,'a lever, B, fulcruined to the opposite end of the plate A, the upper end of said lever project ing above the plate, while the edge of the lower endis sharpened, and a casing, O, attached to the plate and adapted to inclose the lower part of the lever B, substantially as set forth. a

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

REINHOLD BETTER-MANN.
